后记
classpath和classpath*的区别
classpath：只会到你的class路径中查找找文件。
classpath*：不仅包含class路径，还包括jar文件中（class路径）进行查找。
注意： 用classpath*:需要遍历所有的classpath，所以加载速度是很慢的；因此，在规划的时候，应该尽可能规划好资源文件所在的路径，尽量避免使用classpath*。
mapper-locations配置方式
方式一：放在Mapper目录下
yml
mybatis-plus:mapper-locations: classpath*:com/sms/**/mapper/xml/*.xmlpom
<build><resources><!-- 扫描src/main/java下所有xx.xml文件 --><resource><directory>src/main/java</directory><includes><include>**/*.xml</include></includes></resource></resources></build>方式二：放在resource下
yml
# mybatis-plus相关配置
mybatis-plus:# xml扫描，多个目录用逗号或者分号分隔（告诉 Mapper 所对应的 XML 文件位置）mapper-locations: classpath*:mybatis/*Mapper.xml
